Bethany Koby and Daniel Hirshmann of Technology Will Save Us explain how their DIY technology kits and workshops help people "understand what goes into the stuff in our lives" in the penultimate movie filmed at our Designed in Hackney Day.

Technology Will Save Us design kits that contain all the parts and tools needed to build objects such as simple speakers or musical instruments. "A lot of the time it's hard to navigate online resources in order to find all the things you need to make things with technology," says Koby.

Other kits include conductive playdough and programmable bike lights, all sold both online and at small pop-up kiosks they call Haberdasheries for Technology. "These are shops within shops where we can give people information about our kits," she says.

Created with designer Yuri Suzuki, their Radio Kit includes small circuits that fit together like a puzzle to form a working radio. "It contains PCB boards that you can piece together to create connections for a radio," Koby says.

Hirshmann then describes the workshops run by the studio in the local area, which include teaching groups how to wire a plug, solder and create small circuits. "We're interested in creating these workshop experiences where people can come in and join us as a community," he says.

They also arrange "meetings with experts" where they ask people in the community about specific needs that could be solved using simple technologies. "We had a gentleman called Mr Lewis who couldn't hear his doorbell and he wanted to see it," says Hirshmann. The solution was to hook up LEDs from their musical instrument kit to his doorbell so they flashed when it rang. "The key thing to remember is that he was one member in a community that potentially had a similar need, it's possible that this solution could help a lot of people," he says.

The studio also organises technology demonstrations and live "teardowns" of products. "We get an expert to rip apart something that's everyday in our lives, like a toaster, and explain what goes into this thing that makes it so good at making toast," says Hirshmann. "It's really fascinating to understand what goes into the stuff in our lives."

To conclude, he demonstrates light glasses built from their Bright Eyes Kit, which are sunglasses with LED video screens instead of lenses.
